America readies for total solar eclipse

August's total solar eclipse in the US will almost certainly be the most watched such event in history.

More than 12 million people - from Oregon to South Carolina - live on the path of darkness that the Moon will cut as it sweeps in front of the Sun.

Nearly four times that many live within a two-hour's drive. And then there are all the tourists who will flock to America to witness the spectacle.

Angela Speck from the University of Missouri spoke with our science correspondent Jonathan Amos.
